Well I'm torn and confused. I posted in another thread with no response so figured I'd ask here since I haven't seen it from searching. Want to go to a "35" 315-70-17 tire but the Cooper only comes in an "E" rating vs the KO'2 in a "C". With the weight of the 2 door do you think the Cooper's are going to be to stiff for on road driving? I have KO'2s on a 3/4 diesel and have loved them but the aggressive look of the Cooper's have me wanting them bad.

She will probably ride like a lumber wagon on E tires. A buddy had a set of E rated Creepy Crawlies on a JKU and there was no side wall deflection aired down to 8 psi.

That's what I was afraid to hear. I just couldn' find anything related on a 2 door. I don' understand just "E" in that size for cooper but also don't understand a manufacturer offering both a 315-70-17 and a 35-12.50-17 either. Thanks

Well hang on a second. You need to look at the listed tire weights first. Just because a tire is stamped "E" does not automatically mean that it's a heavier, stiffer tire. I've seen lots of situations where a LT-E tire is lighter than a LT-C or LT-D tire from a competitor. I've also seen a few P rated tires that are close to the same weight and stiffness of other LT tires.

Each company uses their own rubber formulations, sidewall construction, tread belt contruction, etc. The overall weight will tell the story. Ignore the load rating.

E’s have a 10 ply sidewall. They will always be stiffer and rougher ride than a C or D. Heavier or not. Now that being said, it’s all personal preference and the 10 ply will always have a bit stronger sidewall which will help in the rocks too.

I'm torn on this because I have KO'2s on my truck and have zero complaints on them but the Cooper's just look so damn good. I drive from construction site to construction site all day and sometimes don't need my truck so will use the wrangler but don't want to get beat up any worse than my 3/4 ton.

No they don't. The sidewalls are 2 or 3 ply on every tire on the market.

The term "10 ply" or "6 ply" or whatever originated back in the old days when tires were actually made with that number of plys in the tread cap. Modern tires do not follow this trend at all.

It's sort of like how people call a F-150 a "half ton truck" even though F-150s have been able to carry more than a half ton for decades.

Again, a tire with overall lighter weight will also be a tire that rides better, regardless of what load rating it is.

I understand that. I didn’t put rated in there because I figured that was a given. E’s will alway be stiffer because of the design of the 10-12-14 ply rated sidewall. Those who have owned trucks or put them on Jeeps inderstand this. The strength and weight rating is always higher on an E rated tire. Hence the rating. The strands of fibers built in are mostly a 2 or three ply, yes I agree. But the rating is completely different and so will be the ride.

Don’t run E’s if you are worried about the ride. You can adjust a lot of it with tire pressure but they will never, ever ride as good at standard pressure than a D or C rated tire. My 37” D’s ride so much smoother
at 32 psi than my 35” E’s did at 26 psi.

Also, don’t even bother with 35’s if you are going with a lift(on a Rubicon). Just put the KO2’s in a 37 on it. They are D’s and are great. Don’t even need spacers if you have a Rubicon.

No lift for me. Yes this is a Rubicon. I had thought about it but I'm afraid the 2 door would look a little out of proportion compared to the 4 door (which looks great with a 2" and 37's in my opinion) so would just like to maybe upgrade shocks later and run 35's.

Ahhh I gotcha. It will look great no matter what.
